The rational design of coal mining machinery improves the efficiency of coal production and reduces the production cost. Basing on specific mining examples, a set of mining machinery system was obtained by technologically analyzing the calculation of production efficiency, as well as the selection of mining machinery, supporting device, and conveyor etc.
The following safe systems of work are recommended to mining operations to assist in the safe operation of shovels and excavators: Conduct an audit of shovels and excavators on site to identify all configurations of actuated access ladders and stairways that could present a crush hazard to workers accessing emergency switches.
A room and pillar system of mining is employed using continuous mining machines, shuttle cars, scoops, and single and dual head roof bolting machines. Coal is transported from the faces by shuttle cars, and out of the mine via belt conveyor. A batterypowered track haulage system is used to transport both personnel and materials.
